1) Best Concert You've Ever Seen
1982 - The Kinks with opening act John Cougar (Mellencamp)
2) Worst Concert You've Ever Seen
Rod Stewart, but partially because my wife insisted on meeting her friends at a bar beforehand, so we missed the opening act who I really wanted to see; Santana.
3) Bucket List Concert
Paul McCartney
4) Concert you wish you could see
I’d say The Beatles, but their later years, and the rooftop concert was too short. Elvis Aloha from Hawaii, but I can watch the video. So I guess The Doors with a cognant Jim Morrison. Or the Monterey Pop Festival.
